Overview of key terms and equations related to impulse, including how impulse can be calculated from a force vs. time graph.

When we calculate impulse, we are multiplying force by time. This is equivalent to finding the area under a force-time curve. This is useful because the area can just as easily be found for a complicated …

Learn what impulse is.

Explore the concepts of momentum and impulse, their definitions, and applications in physics through this educational resource.

Impulse is a change in an object's momentum. The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt).

Action potentials (those electrical impulses that send signals around your body) are nothing more than a temporary shift (from negative to positive) in the neuron’s membrane potential caused by ions …

Impulse is a change in an object's momentum. The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt).

Impulse is a change in an object's momentum. The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt).

When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane. Ca 2 + , which is present at a much higher concentration …
